cleap 0.3.0 released

changelog:

cleap-0.3.0:

BUG FIXES:
- fixed a bug that made the library crash when no opengl context was created on the app (see API new function "cleap_init_no_render").

API:
- new function: "cleap_init_no_render()" is for applications that do not use rendering. The older "cleap_init()" is for software that do create contexts on the app side, therefore they render.
- now private functions differenciate from public ones by prefixing an "_" to the private ones.
- c++ too specific codes are now handled in a "cleap.cc" file. This way can compile *.cc files with special headers like the "tr1/unordered_map" hashmap.
- there is now a "cleap_private.h" header where all private c++ only functions can be declared here.  Functions that include some cuda code should be kept in the *.cu files.
- "cleap_private" includes the public "cleap.h" header, so sources are suficient including just the private header.
- in function _cleap_load_mesh: renamed internal name of the variable "my_mesh" to just "m" for consistency with rest of code. 
- now loading is handled by 2 internal functions: "_cleap_host_load_mesh" and "_cleap_device_load_mesh". This way mantainance is much more modular
- renamed internal variable from auxEdgePointer to aux_tmp_edge
- added a new source file named cleap_glx_contex.cu that handles opengl context creation for GLX systems.
- moved timer functions to private side.

PUBLIC_DOC:
- nothing new, since all changes were for private parts of the library.

PRIVATE_DOC:
- nothing yet, should come in the future when the code becomes more stable.

cleap-0.2.0:

API:
- renamed some variables in "cleap_kernel_utils.cu".
- "cleap_d_angle_adjacent_triangles" is now named "cleap_d_geometry_angle_test".
- small optimizations done to cleap_d_geometry_angle_test.

Documentation:
- removed long nonsense text of "Manual install from binaries" and put small text regarding *.deb install.

Other:
- removed duplicate backup (~) files from the tarball.
- included README file on CPACK package.
