Enabled Cell Vector

Fixed from blender 2.69.8
Round

Utility round(n) instead of only round(x,n)
Random Unit Vector

Similar to Random node but gives a random unit vector in any direction.
Note: Seed is Int, float input works but is converted to int internally
Golden ration

Added phi as constant
Matrix Shear node

Constructs a Shear Matrix using utility function in blender mathutils.
Two factor and a selection of shear plane controls amour of shear.
|| -> // is the shear operation.

Matrix Interpolation

Interpolates matrices from matrix A to matrix B linearly.
If used with value slider number goes from 0.0 to 1.0 and creates the
matrix between.
A list of floats can be used for factor input, then it generates the
matrices between A and B.
According to documentation values between 0.0 and 1.0 should work, but
larger values seem to work as well.
Matrix interpolation

Documentation in source file
Extended Evaluate line

Can now take a list of values to interpolate.
Changed implementation to blenders built in liner vector interpolate
function.
