Added an experimental method to cast a single ray through
different spaces. This method will be used with the dynamic
cube approach.
Added an overloaded method to raycast from current position with
a single ray through multiple spaces. This method is used for the
dynamic approach using cubes.
Changed the raycasting method for the dynamic cube space. The Method
now gets a vector of spaces associated with a tupel of image (u,v)
pixel coordinates as parameters and returns a bool in case of success.
The method seems to work fine at this moment.
Fixed conflicting files.

Minor changes.
Added sensor transformation before traversing a cube. The
reconstruction works nearly.
Added another overloaded method to cast a single ray through a single
TsdSpace. This method is only needed for debugging. Added an inline
method to the TsdSpace to gain direct access to the space. This method
is for debugging only, too.
Added two methods to access the angular resolution and the phi min
members.
Finished adding a new method to cast a ray trough a vector of
TsdSpaces. This method is needed for the cube based approach.
