Now that I've finished updating all the PSL files, I've moved all the PSL files back into the normal examples folder.

Fixed a bug where maude wasn't correctly processing strands that are only executed up to a specific step.

Fixed a bug in the coherence creating code, I made the erroneous assumption that brackets ([) only show up around equational attributes, which is not at all true for meta equations.

Removed the composition specifications (which haven't been implemented yet) from our examples folder.

Fixed a bug where fresh variables were mistakenly treated like regular variables when making sure that variables either show up in the role's input, or has already been seen in a received message.

Fixed a bug where the global variables used in the attack statements in the Maude file were being duplicated, and the duplicates weren't being eliminated properly for some reason.

Added a check to make sure variables in definitions are correct (i.e. they are disjoint from other roles).

Fixed a very subtle bug that sometimes occasionally caused multiple statements to be grouped into a single statement, resulting in nonsensical error messages despite having a well-formed theory.

Moved Amended-Needham Schroeder into done_examples (temporary measure until all of the example theories have been properly converted into the latest Maude-PSL version). Also removed Amended-NS which was just a differently named file of the same protocol as Amended-Needham-Schroeder, and therefore not necessary.

Initial commit to the public repository. Contains all the files needed to run Maude-PSL, as well as an examples directory, and a directory of the original npa-examples for use of comparisions with the Maude-PSL examples. Also contains a pdf file containing a description of the language.
