Class protocol:

queries
o  isAbstract
Return if this class is an abstract class.
True is returned here for myself only; false for subclasses.
Abstract subclasses must redefine this again.


Instance protocol:

accessing
o  _at: index
this is a synthetic selector, generated by the compiler,
if a construct of the form expr[idx] is parsed.
I.e.
foo[n]
generates
foo _at: n

o  _at: index1 at: index2
this is a synthetic selector, generated by the compiler,
if a construct of the form expr[idx1][idx2] is parsed.
I.e.
foo[n][m]
generates
foo _at:n at:m

o  _at: index1 at: index2 at: index3
this is a synthetic selector, generated by the compiler,
if a construct of the form expr[idx1][idx2][idx3] is parsed.
I.e.
foo[n][m][o]
generates
foo _at:n at:m at:o

o  _at: index1 at: index2 at: index3 at: index4
this is a synthetic selector, generated by the compiler,
if a construct of the form expr[idx1][idx2][idx3][idx4] is parsed.
I.e.
foo[n][m][o][p]
generates
foo _at:n at:m at:o at:p

o  _at: index1 at: index2 at: index3 at: index4 put: value
this is a synthetic selector, generated by the compiler,
if a construct of the form expr[idx1][idx2][idx3][idx4] := is parsed.
I.e.
foo[n][m][o][p] := expr
generates
foo _at:n at:m at:o at:p put:expr

o  _at: index1 at: index2 at: index3 put: val
this is a synthetic selector, generated by the compiler,
if a construct of the form expr[idx1][idx2][idx3] := val is parsed.
I.e.
foo[n][m][o] := val
generates
foo _at:n at:m at:o put:val

o  _at: index1 at: index2 put: val
this is a synthetic selector, generated by the compiler,
if a construct of the form expr[idx1][idx2] := val is parsed.
I.e.
foo[n][m] := val
generates
foo _at:n at:m put:val

o  _at: index put: val
this is a synthetic selector, generated by the compiler,
if a construct of the form expr[idx] := val is parsed.
I.e.
foo[n] := val
generates
foo _at:n put:val

o  dimensions: aPointOrArray
set the dimensions vector;
provides the number of indices per dimension

o  setDimensions: anArray
set the dimensions vector;
provides the number of indices per dimension

queries
o  isMultiDimensionalArray
true if this is a matrix-like collection

o  isSquare
true if this is a square matrix

species instance creation
o  speciesNew: size
create a new instance of my species.
MUST be redefined especially for MatrixAccessor
