Test implementation of Sample Elimination Algorithm

[WorkGitAccount]

References #13

The cySampleElim.h class handles the poisson disc sample elimination algorithm. Run and test this class through python.

• Verify cySampleElim class binding and linking with python
• Write example code that demonstrates a working Sample Elimination Algorithm
• Write and verify unit tests including tests for each function:
  - [] WeightedSampleElimination()
  - [] Eliminate()
  - SetTiling()
  - SetWeightLimiting()
  - GetParameters()
  - GetMaxPoissonDiscRadius()

Stepped through the cySampleElim class paying special attention to data types, syntax, and parameter handling.

The cyCodeBase has been hardcoded to link with matlab and will need to be updated.

It is possible to only link to PcCoarsen2D which calls this class. However linking to cySampleElim will allow the python library to interact and run unit tests. Users will be able to study and engage with the algorithm.

The class and sample elimination algorithm are well documented by the author Cem Yeksel ( Sample Elimination for Generating Poisson Disk Sample Sets ) . The algorithm could be implemented in python with a simple case as a demo. As part of the project documentation, a script to run an animation could help visualize the elimination algorithm and blue noise characteristics.

Wrote Python script to generate input sample data focusing on a finite base case. Stepped through matlab data structures created at breakpoints simultaneously with python. Drafted ways to automate this process.

Successfully compiled a shared library of just the cySampleElim class with bindings for python for testing. Verified creating an elim object from python and calling member functions.

Added python function to generate input data. Wrote test cases.

Got all the bindings to work except Eliminate(). It is an overloaded function that takes a lambda function as the weightfunction when overloaded. The syntax to get this all to work is extremely complicated (binding overloaded function with optional lambda weightfunction).

Eliminate() can be effectively tested when it's calling class PcCoarsen is binded and tested in another task. This simplifies testing and focuses efforts on the first milestone.
