描述----------Description----------
Forward gene selection is usually a computationally expensive task. To reduce the computation expense one may want to do not consider one gene at a time but chunks of genes. This class store the sizes of gene susbets to be
提出基因选择通常是计算昂贵的任务。为了减少计算费用，可能需要不考虑在时间，但大块的基因的一个基因。这个类商店的基因susbets的大小是
创建对象----------Creating objects----------
new("geneSubsets", optionValues)
new("geneSubsets", optionValues)
Create a geneSubsets, the sizes of the different subsets are determined by optionValues. The size of the biggest subset maxSubsetSize and the number of subsets to be tried noOfOptions are automatically deducted. The speed is set to high is there are less models than the size of the biggest subset and 'slow' if not.
创建一个geneSubsets，不同子集的大小确定optionValues。规模最大的子集maxSubsetSize和亚群的数量要尝试noOfOptions被自动扣除。速度设置为high是有比最大的子集和“慢”，如果没有大小的模型。
new("geneSubsets", maxSubsetSize, speed="high")
new("geneSubsets", maxSubsetSize, speed="high")
Create a geneSubsets, with a biggest subset of size maxSubsetSize. If the speed is high the sizes of the subsets are increased by a power of 2 from 1 to the biggest power of 2 smaller than maxSubsetSize. If the speed is slow the sizes of the subsets are increased by 1 from 1 to the maxSubsetSize.
创建geneSubsets，最大的子集的大小maxSubsetSize。如果speed是high从1到2的幂的最大功率为2比maxSubsetSize小的子集的大小增加。如果速度slow子集的大小增加1从1到maxSubsetSize。
插槽----------Slots----------
maxSubsetSize: numeric. Size of the biggest subset
maxSubsetSize：numeric。规模最大的子集
optionValues: numeric (vector). Sizes of the subsets in acsending order
optionValues：numeric（矢量）。在acsending为了子集的大小
noOfOptions: numeric. Total number of subsets
noOfOptions：numeric。子集的总数
speed: character. Speed of the backward feature selection. high if the number of models is smaller than the size of the biggest subset,
speed：character。落后的特征选择的速度。 high如果车型的数量小于最大的子集的大小，
方法----------Methods----------
Retreive and modify the size of the biggest subset (slot maxSubsetSize)
Retreive和修改的规模最大的子集（槽maxSubsetSize）
getOptionValues(geneSubsets), getOptionValues(geneSubsets)<- Retreive
getOptionValues(geneSubsets), getOptionValues(geneSubsets)<-Retreive
getNoOfOptions(geneSubsets) Retreive the total number of subsets
getNoOfOptions(geneSubsets)Retreive总数的子集
getSpeed(geneSubsets), getSpeed(geneSubsets)<- Retreive and modify the speed of
getSpeed(geneSubsets), getSpeed(geneSubsets)<-的Retreive和修改的速度
