#2797:

• Updated PSO to make it more compatible with SPSO 2011
• Removed truncation of velocity vector and instead rescaled it given the maximum velocity
• Added non-zero initial velocity according to SPSO 2011
• Removed complicated bouncing code due to box constraints and instead implemented as described in SPSO 2011
• Calculating neighbor best has been changed to use personal best
• Avoiding local and global particle update and instead relying on neighborbest
• More randomization during velocity update by using a separate random numbers per dimension
• Reusing problem specific solution creator in RealVectorParticleCreator instead of always using UniformRandomRealVectorCreator
