[algorithm] Refactor PR #5 - Remove needlePts variable

[th-skam]

Info & Merging

• A series of PRs to clean-up and simplify the algorithm, and make it easier to make additions in the future.

Dependencies

• After PR [algorithm] Refactor PR #4 - Proper iterator use #50

Changes

• The needlePts variable is not needed since the algorithm re-projects proximities on the needle shaft at every time step.

Did you introduce the m_needlePts or was it already there?

[th-skam]

The m_needlePts was introduced by me. At that time, we were storing the proximities on the needle. Now, we are re-projecting the proximities stored in m_couplingPts back on the needle geometry. There is no need to store them because we re-compute them at every time step and do a push back at the insertionOutput in place.
