#309 fixed button to restore profile window harg chrfi

we really need a button that reopens the profile window. At present if the window is closed the program keeps running but there is no way to get the window back again. this means if the user closes it they will have to restart lag (and incur large loading times).

#310 fixed have multiple resolution versions of quadtree stored at one time chrfi chrfi

basically the quad tree will contain buckets containing different resolutions. the quadtree will still be built at full resolution (or whatever resolution is specified in the constructor. the user will be able to request buckets from subset that contain a lower resolutions. This will mitigate the fact that as buckets are chached as a whole the entire bucket must be cached to access only a single or few points.

#311 fixed drawing the flight lines increases main memory usage emca chrfi

to reproduce load several flight lines that will not fit within the given cache. these will load normally with the ram usage being capped at the cache limit. when the image is first drawn the amount of ram being used by the program will increase. This increase seems to be linked to the size of the flight lines. subsequent redraws increase the ram usage slightly but i think this is the same problem being caused by drawing areas that were in cache the first time but now have to be loaded.

once each part of the image has been drawn and loaded out of secondary memory once the increase stops. This at first seems to point to a problem in the caching code and therefore i have used my test bed to perform unit tests on the quadtree and caching classes. These tests showed that without the gui loading and then pulling points out of uncached buckets has no effect on the ram usage of the program.

so far the only theory is that it is caused by an overflow from the graphics card ram.
