Remove class EDInputSource

[wmtan]

This PR removes the superfluous class EDInputSource, moving its functionality into PoolSource, where it should have been in the first place. This PR reduces the depth of the PoolSource inheritance tree by 1,
reduces the number of lines of code by 68, reduces the number of files by 2, and results in simpler, more maintainable code. Altogether, a win-win.
