ITSLM pattern documentation guidelines

In order to maintain a consistent approach to documenting patterns, the following guidelines are to be followed in documenting patterns on the ITSLM wiki.

Main headings
The main sections of each pattern follows the model put forward by Christopher Alexander.

Secondary headings
The three main sections (pattern name is not really a section) are further divided into subsections following the general structure laid out by Gamma et al., with allowances for differences in the nature of pattern specifics.

Within 'Consequences'
Describe the consequences of implementing the described solution.
