Macros for testing nom parsers

Often when I'm testing nom parsers, I end up defining a lot of little macros like this, so I thought I would bundle them all up into a crate so I didn't have to define them over and over

Macros

assert_done	This macro checks to make sure that the IResult it is passed is Done
assert_done_and_eq	This checks that the IResult is Done, and lets you check that the value returned as the O type of the IResult is equal to the second parameter
assert_empty	Internal only, really, and not even necessary :P
assert_error	This asserts that the IResult is an Error
assert_error_and_eq	This asserts that the IResult is an Error and that the error is what is expected
assert_finished	This does the same thing as assert_done!, except that this also asserts that the input slice is empty
assert_finished_and_eq	Same as assert_done_and_eq!, but asserts that the input slice is empty
assert_needed	This asserts that the IResult is an Incomplete
assert_needs	This lets the user specify how much input the parser should need
