loading fasd clobbers z(), and results in a cryptic syntax error
message, since 'z' is already an alias when z.plugin.bash is being
sourced.
this conditional detects this situation and returns early.

contain a shebang line, and should be a+x.
cite about-plugin metadata. This could be retrieved later, say by an
install script or other helper function, with:
cat ~/.bash_it/plugins/enabled/base.plugin.bash | metafor about-plugin
In this way, summaries of each plugin may be provided to give newcomers
(like me!) an overview.
also, rewrote plugins-help(), which didn't work very well on my system.
It now dynamically queries composure metadata.
The [fasd](https://github.com/clvv/fasd) project replaces the current
z() functionality, and generalizes it for all files and directories.
It provides a 'z' alias which works like z() does today, but faster, as
well as 'f' for selecting files, and 'd' for selecting directories, all
based on 'frecency' with Bayesian inference calculations. It is also
trivial to set up a 'v' alias to edit frecently used files.
Seriously, two points just for using Bayes' theorem.
I've sourced this as a plugin, and made a minor modification to @clvv's
0.5.4 file to bootstrap the initialization process without installing
fasd outside of Bash_it, or modifying the PATH.
This doesn't fully install fasd on a system (for instance, the man page
is not installed).
Using this as a plugin will clobber the z plugin.
This also installs a PROMPT_COMMAND hook. I don't have a complex setup,
but it is possible this may not play nice with other PROMPT_COMMAND
hooks if they are set. It seems to work well on my box.
As an aside, it appears that z.bash is out-of-date compared with @rupa's
latest code.
