Adjacency matrix import

Adjacency matrix is used to represents edges between nodes in graphs. As you may know, a topic map is also a graph where edges are called associations and nodes topics. Wandora's adjacency matrix import feature takes a matrix, interprets it, and creates topics and associations according to the matrix.

Adjacency matrix contains 0 (zeros) and non-zeros. Whenever a matrix cell is non-zero, an association is created between row-topic and column-topic. For example is matrix cell in second column and third row contains value 1, then an association is created between topic 2 and topic 3. Numbers 2 and 3 represent here topic identities.
