Description:

a very special dictionary-like collection,
which effectively maps characters to values.
API:
    the API is similar to a dictionary, but only characters
    are allowed as keys.

implementation:
    uses fast direct indexed access instead of hashing


[instance variables:]
    {InstanceVariable: pages Class: Array}

Class protocol:

 new

return an initialized instance

Instance protocol:

 at: aCharacter

(comment from inherited method)
return the indexed instance variable with index, anInteger;
this method can be redefined in subclasses.

 at: aCharacter ifAbsent: exceptionValue

}

 at: aCharacter put: something

}

 growPagesTo: pageIndex

 do: aBlock

(comment from inherited method)
evaluate the argument, aBlock for each element.
Return the receiver
(subclasses should care to also return the receiver,
in case do: is used in a chain of messages.)

 keysAndValuesDo: aTwoArgBlock

(comment from inherited method)
evaluate the argument, aBlock for every element in the collection,
passing both index and element as arguments.
Blocked here - must be redefined in subclasses which have keyed elements

 initialize

(comment from inherited method)
just to ignore initialize to objects which do not need it
