- added new ZoomIntoRay() method which allows to create new rays around a given one using a specified angular resolution

- made indicing methods protected
- added new boolen method Is2D()

- added function to estimate wavefront surface at given timestamp
- added function to calculate wavefront surface assuming (homogeneous) spherical wave

- minor bugfixes

- cleaned up code
- renamed GetSurroundingGrid() to SurroundingGrid()
ART - AdaptiveRayGrid:
- added variable storing the resolution of theta and phi
ART - Eigenray Worker
- addes some TODOs

- finished test for AdaptiveRayGrid

- now has once double resolution function for theta and phi respectively
    - phi-function now also checks whether phi is circular
    - phi-function also uses modulo 360
- fixed multiple out of bounds errors in DoubleRayResolution()

- added function to get circular bool
- fixed bug that occured erasing last element in angle vector

- fixed a bug in constructor where angles where not properly converted to normal vector

- RayGrid now has a get function to access a ray via theta and phi index
- AdaptiveRayGrid is now publicly derived from RayGrid

- bugfix

- fixed indicing bugs
- fixed bug in Contains() method
- moved some definitions to cpp file

- added test for AdaptiveRayGrid

- removed multiple bugs where base constructors where called within constructor body

ART - RayGrid & AdaptiveRayGrid
- UniqueRays() now returns const reference

- doubling the ray resolution now does not create new rays at poles

- changed a few functions to be protected and added inline keywords
- added protected get method for ray matrix
- fixed bug where a float was tested with double epsilon
- added function to check for pole direction using a theta angle

- now expects a unique set of rays

ART - RayGrid
- now additionally stores unique set of rays, only this can be accessed publicly
- ray matrix is now private and can be adjusted using protected set method

ART - AdaptiveRayGrid
- NewRaysOfLastAdaptation now is also a set instead of a vector

- renaming of files - part 2: includes

- renaming of files - part 1
- moved header to include

- renaming of ray grid adaptation class

- part 2: internal renamings

- part 1: files

- added functions for advanced ray zooming

- added function to filter for rays using indices for theta and phi
- also added functions to get rays of same theta/phi respectively

- added < operator for RayElement
- added method to get data at certain timestamp using nearest neighbor

- removed unnecessary function ConstRayVectorReference()

-additional performance improvements by using references

- creating new vectors now allocates memory first
- get functions for vectors now return const references

- moved all definitions to cpp

- moved Worker code to individual files

- renamed namespace from Export to Utils

- now is derived from std::vector

- moved most definitions to cpp file

- RayGrid: renamed a few functions
- RayResolutionAdapter: is now private derivation of RayGrid

- defined Run functions as const

- bugfix regarding export

- renamed functions which creates a copy with new rays
