clean up in MinimalPolynomial.g
extended example.g
added missing argument description strings
fixed creation of unit row vector
coding style
issue an error in MinimalPolynomial of ring element

if first basis vector is not the identity of the ring
split operation/method docu for MinimalPolynomial
declared and installed SquareFreeFactors
installed Value for [ IsHomalgRingElement, IsHomalgRingElement ]
declared and installed the property IsIrreducibleHomalgRingElement

together with convenience method IsIrreducible

(needs Modules v2013.09.14)
added example for SquareFreeFactors
declared, installed and added example for SeparablePart for univariate polynomials over perfect fields.
Created a new gd/gi file: RadicalComputation
Missed these lines in the last commit: Creating RadicalComputation.gd/gi files
declared, installed and added example for RadicalForHomalgIdeal.
Computes the radical of a zerodimensional Ideal, so far just for rings with perfect coefficient field.
declared, installed and added example for PolynomialEmbeddingmatrix.
(Forgot the special name for this matrix)
Created new files: PrimaryComputation.gd/gi
declared IsPrimeZeroDim and installed the first part of the algorithm.
declared and installed IsPrimaryZeroDim
