Operation description not correct - list@File

[SuperMauro1966]

The operation description in copied from StringUtils, and doesn't represent the correct semantic.

Please look at the pull request I am going to submit to fix this.

@thesave it seems that the doc generator does not correctly generates operation comments. In the case of list@File it reports the same description of getSize operation as reported below. If you check the related include file, operation list does not have any description associated.
