rmoo v0.2.0

1. Considerable changes made to the rmoo package:

• All the algorithms implemented in rmoo will now be called through the rmoo() function, passing the strategy to be used as a parameter.
• New s4 methods created, the functions scatter(), pcp(), heatmap() and polar() will be called by the plot method and passing the object and plot type.
• s4 methods: summary() and print() for brief verification of returned results.
• Summary() function deprecated: Now it is executed by the s4 method progress(), the method is used within the execution.
• Other s4 methods created are getFitness(), getPopulation(), getDummyFitness(), getCrowdingDistance(), getMetrics(), they were created so that the user does not need to directly access the object slots.
• The structure of classes and inheritance were improved, following the rules of object-oriented programming.

2. Bugs Fixed:

• The non-dominance process was solved, an error was generated when the first front was only made up of one individual.
• ecr, cdata, dplyr, reshape2 packages are now suggested and not imported.
• Only the packages that are exactly necessary or that generate errors if they are not imported are found in import.
