added testCases and implementation of method areVectorsParallel to BasicVectorMathematics, made clear distinction which methods are concept specific mathematics and which are reusable standard mathematics algorithms e.g. parallel vector identification
added boundary tests for method calc Angle between 2 vectors
added boundary tests for method calc Angle between 2 vectors
added boundary tests for method calc Angle between 2 vectors
small comment correction
implementation+first test cases of middle point calculation
implementation+first test cases of meeting point calculation of two lines
added class MinimalDistanceResult, splitted method minimalDistanceBetweenLineSegments into two cases
started to implement complicated minimalDistanceCalculation algorithms
