The Matlab Type Provider is slow on non-SSD machines

[Rickasaurus]

Currently the filesystem is walked and functions are parsed repeatedly, leading to unacceptable behavior on machines without fast disk access.

I suspect an intelligent function cache is the best solution, as there is no direct way to discover functions via the console.

[Rickasaurus]

Two other options:

1. provide an executable which will build the function cache on slow machines
2. use a data structure inside of matlab to keep track of matlab related metadata.

Howard suggested that this might be mitigated by initially polling just root toolboxes and loading the rest lazily. To do this each of them would need to be a namespace with lazily loaded objects in it.

Potential Fix in commit 17aaae2
Now lazily parsing/querying for matlab functions. This will probably fix the issue but it needs to be tested on a machine with a slow disk.
