描述----------Description----------
Imports csv file holding field recorded data returning a list holding field and other key data provided as arguments.
进口csv文件，记录的数据返回一个列表保存领域和其他关键数据作为参数提供的。
Field measures to be taken on logs and branches include:
现场log和分支机构应采取的措施包括：
Azimuth (azimuth): mean angle of orientation of the branch or log measured from the base of the tree (usually with magnetic north as reference, measured clockwise), mandatory
方位角（azimuth）：指的方向角的分支或登录从该树的根（通常与磁北为基准，顺时针测量）测得的，强制性的
Diameter at base (dBase): diameter at insertion point on the stem, for branches, diameter of the lower section for logs, mandatory
在底座直径（dBase）：在插入点上干，树枝，下部直径的原木直径，强制
Diameter at top (dTip): always 0 for branches, diameter of the higher section for logs, defaults to 0, mandatory only for logs
在顶部直径（dTip）：始终为0的分支，直径只对原木的高区的log，默认为0，强制
Length (length): length of logs or branches, mandatory for logs, mandatory for branches only if their slenderness coefficient is to be
长度（length）：长的，强制性的log，log或分支机构强制性的分支机构只有在其柔度系数是
Distance (tipD): length of branch or log projection on the ground, starting from tree base to tip of branch or log, mandatory
距离（tipD）：长度的分支或log投影在地面上，从树碱基给小费的分支或log，强制
Height (height): height of branch insertion on the stem or height of lower section of the log, to be used to compute z coordinate of CM, defaults to NA, mandatory only for z
高度（height）：上干下段的log或高度，高度分支插入被用来计算z协调的CM，默认为NA，强制只z
Tilt (tilt): mean branch tilt or log tilt from the horizontal plane (eg a vertical branch is 90 degrees, an horizontal branch is 0 degrees), to be used to compute z coordinate of CM, defaults to 0, mandatory only for z determination of CM. Note however that the tree tip should be considered as a branch, not a log, in order to account for foliage biomass. In this case the tilt value should be recorded otherwise it would default to 0,
倾斜（tilt）：平均分支倾斜或log倾斜从水平平面（例如，一个垂直的分支是90度，水平分支为0度），可以用来计算z的CM协调，默认为0，只z确定CM强制执行。然而，树头应该考虑的一个分支，而不是一个log，以帐户为叶生物量。在这种情况下，应记录的倾斜值，否则将默认为0，
To be pruned (toBePruned): a boolean value, defaults to FALSE,
修剪（toBePruned）：一个布尔值，默认为false，
Path to tip (pathToTip): a boolean value TRUE on logs and branches that make part of the “main stem” of the tree,
给小费的路径（pathToTip）：一个布尔值TRUE，使树的“主干”上的log和分支机构，
用法----------Usage----------
importFieldData(fileName, dst, branchesAllometryFUN,
bCM = 1)
参数----------Arguments----------
参数：fileName
Name of csv file holding field data
csv文件的名称举着数据
参数：dst
Fresh density of wood of the tree
新鲜的树的木材密度
参数：branchesAllometryFUN
the function that should compute branch biomass from its diameter
应计算分支生物量的函数，该函数从它的直径
参数：bCM
Estimated position of the centre of mass of branches, a real number from 0.01 (CM at branch base) to 1.00 (CM at branch tip). As a rule of thumb, average live branches, with an average amount of foliage, have CM approx. from 1/3 to 2/3 of their length. bCM = 1.0 (default value)
预计大规模的分支，一个实数从0.01（CM在分支碱基）至1.00（CM在分支的顶端）的中心位置。作为一个经验法则，平均活的分支，与枝叶的平均金额约CM。从1/3到2/3长度。 BCM = 1.0（默认值）
值----------Value----------
a list of 4 elements: field data, wood fresh density, allometryFUN function and branches CM
4个元素：“字段中的数据的列表，木材新鲜的密度，allometryFUN功能和分支CM，
