/**
 * This class generates data for the schema located in Contact.sql
 *
 * each public method generates data for the concerned table.
 * so for example the addContactDomain method generates and adds
 * data to the contact_domain table
 *
 * Data generation is a bit tricky since the data generated
 * randomly in one table could be used as a FKEY in another
 * table.
 *
 * In order to ensure that a randomly generated FKEY matches
 * a field in the referened table, the field in the referenced
 * table is always generated linearly.
 *
 *
 *
 *
 * Some numbers
 *
 * Domain ID's - 1 to NUM_DOMAIN
 *
 * Context - 3/domain
 *
 * Contact - 1 to NUM_CONTACT
 *           80% - Individual
 *           10% - Household
 *           10% - Organization
 *
 *           Contact to Domain distribution should be equal.
 *
 *
 * Contact Individual = 1 to 0.8*NUM_CONTACT
 *
 * Contact Household = 0.8*NUM_CONTACT to 0.9*NUM_CONTACT
 *
 * Contact Organization = 0.9*NUM_CONTACT to NUM_CONTACT
 *
 * Assumption is that each household contains 4 individuals

/**
 *
 * Note: implication of using of mt_srand(1) in constructor
 * The data generated will be done in a consistent manner
 * so as to give the same data during each run (but this
 * would involve populating the entire db at one go - since
 * mt_srand(1) is in the constructor, if one needs to be able
 * to get consistent random numbers then the mt_srand(1) shld
 * be in each function that adds data to each table.
