Result Text and Individual File Result Cleanup

[nbollis]

Some issues were created in the most recent PostSeachAnalysisTask refactoring.

Result Writing Adjustments

• Adjusted peptide/proteoform results to use the correct label when outputting.
• Moved the creation of individual file results directory from the WriteProteinGroups method to main method in PostSearchAnalysisTask
• Adjusted the output to say <= 0.01 instead of = 0.01 for all result.txt summary lines.

Additional Tests

• Added test to ensure that the Result.txt has the correct result types (peptide/proteoform) and correct number of consensus/individual file result summary lines.
• Added test to ensure that the correct number individual file result files were written out and had the correct name.

Test Refactoring

• Combined both SetUpFixtures within the Test Project.
• Adjusted the PostSearchAnalysisTaskTest to pull their search data from a test case to reduce redundant searches.
• Each test case will only be searched one time and the results can be pulled from the respective output directory.
• The test cases are disposed (directory containing results deleted) at the very end of all test running as found in the SetupTest.GlobalTearDown method.
