Test input:
glob is I
prok is V
pish is X
tegj is L
glob glob Silver is 34 Credits
glob prok Gold is 57800 Credits
pish pish Iron is 3910 Credits
how much is pish tegj glob glob ?
how many Credits is glob prok Silver ?
how many Credits is glob prok Gold ?
how many Credits is glob prok Iron ?
how much wood could a woodchuck chuck if a woodchuck could chuck wood ?

Test Output:
pish tegj glob glob is 42
glob prok Silver is 68 Credits
glob prok Gold is 57800 Credits
glob prok Iron is 782 Credits

-------Notes-------------
Test plan has the following tests:

End to end test from file
	It covers the main test cases reading from a file.

End to end test from Console
	It covers the main test cases reading from the console. It's an asynchronous test.

UNIT TESTS

Test Instruction Reader Builder
	It test that the Instruction Reader gets properly created from the args passed in main:
		Test build standard input reader
		Test build file input reader
		Test builds standard input reader when no args are passed

Test Instruction Reader
	It test the method readInstruction, reads one line at time. 
	It does NOT test the method readInstructions!



TestRoman
	It test romans are converted to arabic

Test Galaxy Agenda
	One test with all the main cases. This test is redundant but it helps to test all the scenarios at this level, API level.

	Test Galactic to roman
		This test could be a TestGalactic class.
		Convert galactic to Roman
				This test is an middle step to convert galactic to arabic, it could maybe be deleted since the funcionality is tested within the next test, 
				plus it could be testin implementation details (the fact we convert to roman, previous that we convert to arabic is just the way we implemented).
				For example we could change the implementation to use a conversion table galactic/arabics and use the roman algorithm directly (exercise pendent*).
		Convert galactic to arabic
		    	Check "glob pish" is 9

	
	Add Galactic Note
		Test adding a simple galactic note sets the correct value: "glob is I", returns I.
				
	2.4 Add Equation Note (agenda.addNote("glob glob Silver is 34 Credits"))
			This test checks the Silver is added to the conversion table with value 17
		2.4.1 Test build equation ("glob glob Silver is 34 Credits" --> equation.coefficient="glob glob", equation.variable="Silver", equation.constant=34")
			Its again an middle step to get the previous test passing. 
			It test as well decimals: iron is 78.5
			
			2.4.1.1 Test build galactic currency (glob glob Silver --> galacticCurrency.galactic= "glob glob", galacticCurrency.currency="Silver")
				This test it could maybe be removed as well, since it is testing quite low, it is testing implementation details and it is cover by the previous 
				one and the "add Equation note" test.
			
		2.4.2 Test solve equation (equation.coefficient="glob glob", equation.variable="Silver", equation.constant=34" --> return constant.divide(coefficient))
				Given an equation it return the variable value by dividing the constant between the coefficient.
			
	2.5 Test ask galactic number ("how much is prok glob ?"
		Given the galactic numbers are already saved, it tests the retrieving part of the agenda and displays the right message
	
	2.6 Test ask equation ("how many Credits is glob prok Silver ?")
		Given galactic numbers and currencies (silver) are already saved retrieved them and displays them correctly.
		
	2.7 Test invalid entry ("how much wood could a woodchuck chuck if a woodchuck could chuck wood ?"
		Test the agenda handles an invalid question.
		
		Handle the following invalid entries
		agenda.ask("glob is I") --> is not a valid question
		agenda.addNote("how much is glob ?")--> is not a valid note
