Largely re-writing motivation and methodology sections in line with tasks 1-9 of #119

Particularly tries to clarify the differences between clustering and PCA/FA from the outset (even though they're completely different methods, I think a reader would benefit from this being apparent immediately).

Also moves the section on believing in clusters to after the method is explained - I think how to believe in a cluster is easier to understand if we know what clusters are fully first

mainly to motivate by clarifying differences compared to pca and fa since these are already discussed
think it's clearer to explain believing in clusters after fully describing what clusters are
unclear what a specified clustering algorithm is and how this increases our confidence that data can be partitioned into groups at this stage
…t convergence looks like, tasks 8 and 9

Picking initial points randomly here may be misleading for someone just looking up the method from this section. Have simply omitted and said that this is discussed below. Also, have removed the word convergence in favour of a description of what convergence looks like
